RAIL-TIE AND FASTENER.

Specification of Letters Patent. Patented Aug. 2'? 1912.

Application filed July 26, 1911. Serial No. 640,679.

b all whom it may concern Be it known that I, GRANVILLE A. HUMA- soN, acitizen of the United States, residing at Shreveport, in the parish ofCaddo and State of Louisiana, have invented a new and useful Rail-Tieand Fastener, of which the following is a specification.

This invention relates to rail ties and fasteners and more particularlyto means prlmarily designed for use in connection with a concrete body,whereby rails may be securely fastened to the tie and will, at the sametime, be held positively againstspreading.

A further object is to provide a structure of this character includingseats for the reception of the bases of the rails, there being railengaging devices combined with the structure and overhanging the seatsso as to hold the rails securely within the seats, the walls of saidseats receiving the side thrusts of the rails and thus reducing, totheminimum, danger of the rail fastening devices being wedged or priedoff of the structure to which they are attached.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination, andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings, the preferred form of the invention hasbeen shown.

In said drawingsz Figure 1 is a view partly in elevation and partly inlongitudinal section of the improvements constituting the presentinvention, the middle portion of the structure being removed. Fig. 2 isa plan view of the parts shown in Fig. 1. Fig. 3 is an enlarged sectionon line A-B Fig. 1. Fig. l is an enlarged section on line CD Fig. 1, theconcrete tie body being shown in position under the tie bar and thecushion interposed between the bar and the tie body being shown insection.

Referring to the figures by characters of reference 1 designates ametallic tie bar having upturned ends forming shoulders or abutments 2and formed within the upper face of the bar adjacent the ends thereof ll 1 l l j l are longitudinal grooves or channels 3. One of these groovesor channels 18 located adjacent each end of the bar and the two channelsaline, the abutments 2 constituting continuations of the outer end wallsof the channels 8 while the inner end walls of the channels form stopshoulders or abutments 41-. Bolt holes 5 are formed in the bar and openinto the channels 3 and the walls of the channels are cut away, adjacenttheir centers, so as to form rail seats 6, each seat being of the samewidth as the base of the rail to be fastened and the walls of the seatsextending perpendicularly from the bar 1 so as to constitute abutmentsfor the rails, as indicated at 7.

'Each of the channels 3'is adapted to receive two oppositely disposedrail fastening devices. Each of thesedevices includes a block8 having acentral longitudinal rib 9 so proportioned as to fit snugly within thechannel, the block 8 being of the same width as the bar 1 and adapted tolie flush thereon.

One end of the block bears against one of the abutments 2 or 4 while theother end thereof has a rail engaging jaw 10 so shaped as to fit snuglyupon one of the base flanges of a rail and to fit against one side ofthe web of the rail. Openings are formed within the blocks 8 and areadapted to receive bolts 11 which may be held in place means of nuts 12or the like. The tie bar and the rail fasteners herein described areadapted to be used in connection with tie bodies of any preferred typebut preferably in connection with concrete tie bodies. For example, andas shown in Fig. 4:, the concrete tie body 13 may be formed with a.channel 14 in which the bar 1 is seated, there being a cushion underthis bar and within the channel 13. Said cushion, as shown in Fig. 1-,is made up of strips 15 which are V-shaped in cross section and areassembled closely together, each strip being disposed oppositely to thenext adjoining strips. It is preferred to form one strip of cottonfiber, the next adjoining strip of cork and the next strip of rubber.These cushioning strips completely fill the spacebetween the bottom ofthe channel 1 1 and the lower face of the tie bar 1. Then the tie bar isused in connection with a tie body such as indicated at 13, the bolts 11are preferably on tended entirely through the tie body 'instead ofprojecting solely through the tie bar and the rail fasteners.

It will be apparent that when rails are mounted in the seats 6, thewalls 7 of these seats will constitute abutments for the sides of thebases of the rails and will thus receive the side thrusts and hold therails positively against lateral movement. The fas tening deviceslikewise constitute efficient means for holding the rails againstspreading because the outer blocks abut against the upturned ends 2.Both blocks bear against the sides of the rail base therebetween and theribs of the inner blocks abut against the end walls 4: so as'topositively hold the inner blocks against longitudinal displace ment. InView of the fact that the ribs as well as the walls 7 bear against thesides of the base flanges, it will be seen that there is no danger ofthese base flanges wedging between the tie bar 1 and the blocks 8 andthrusting upwardly upon the nuts 12 or bolts 11, thus tending to breakthem. More over as the rail fastening blocks are positively held againstlongitudinal movement by the abutment of the ribs against the baseflanges of the rails and against the abutments 2 and a, it will be seenthat the bolts 11 are subjected to no strain due to the side thrusts ofthe rails.

What is claimed is l. A device of the class described including a tiebar having a rail seat in the upper face thereof and aiminglongitudinally extending channels extending in opposite directions fromthe seat, there being an upstanding abutment at the outer end of one ofthe channels, rail fastening devices upon the tie bar and overhangingthe seat, said fasteners having longitudinal ribs remo-vably seatedwithin the channels and abutting against the end Walls thereof, andadapted to abut against the sides of the base flanges of a rail on theseat, and means extending through the bar and ribs for detachablysecuring the rail fastening devices upon the bar. 7

2. A device of the class described including a tie bar having upturnedterminals and longitudinally extending channels, there being railseatswithin the upper face of the 1 bar andintersecting the channels, railfastening blocks extended throughout the width of the bar and bearingoutwardly against the terminals, rail fastening blocks mounted upon thebar and between the seats, rail engaging jaws extending from the blocksand overhanging the seats, longitudinal ribs upon the blocks and mountedwithin the channels, and means extending through the bar and blocksfor'detachably securing the blocks upon the bar.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
